SHEET. FEEDING AND ASSOQIATING MECHANISM.

Application filed October 6, 19%.

This invention relates to certain. improvements in sheet feeding and associatingmeclr anisms.

In i'fast rotary hunting machines it frequei'itly desirable to feed in a previously printed sheet, such as an, insert or a cover, and to associate these sheets with the product oi the press. These iepecially or pre viously printed sheets are fed into thejmachine by autoi aatic sheet-feeding mechanisms. In "Fast rotary machines, however, the speed at \vhich the products are delivered from the printing machines usually much higher than the s-zpeed at which the automatic slicet-i ceders can be operated "to feed in the sheets To utilize the capacity oil? a high speed machine, therefore, it has been neces ary to provide two or more fooders. These feeders are expensive, thus adding considerably to the cost of a press, complicatethe ljnj'c s, and, 'lurtherniore, with certain types of"- presses, it very inconvenient, if not impossible, to position more than one tender in the desired relation with the prlntinnmachine.

It is the particular ohject of the present invention to produce a sheet-feeding mechanisln \vhcrehywith one sheet-feeder the specially printed sheets, as covers or inserts, may be fed to a high speed rotary machine and associated with the products therefrom so that the machine may he run to capacity, either with collected or uncollccted associated products.

It is a further object of the invention to produce a feeding mechanism which will be simple, economical to construct, and which may be positioned in any desired relation with the press with which it is to he used.

'With these and other objects not specifically referred to in view, the inVentioncOn sists in certain novel parts, arrangements and combinations which will he "fully described in connection with the accon ipanying drawings and the novel features thereof pointed out in the claims hereunto annexed.

Generally speaking, the objects of the invention are carried into efi'ect by the use of n'iultiple sheets, that is,-a sheet consisting o't several similar sheets, covers or inserts, printed in Ol1,&11(.l "in the provision of a mechanism for separating this miiltiple sheet into single sheets and feeding the single slan into the machine in correct, timed re- Serial No. 741,803.

Figure shows a modification of the construction shown in Fig. 2}, where. compactness of parts is necessary 6r desired.

Referring now to these drawings, the

slieet-feeding' mechanism is arranged at the 'i older end of a printine; machine. the cutting cylinders of which those marked 1, 2, are

illustrated, the various parts of the mechanism being supported in frames 3 of any .sual or desirable configuration. From the cutting cylinders the product, which may be an associated product is led between for warding rolls 4;, 5, to the folding; mechanism which may be arotary folder including a and this multiple sheet is cut into single sheets and the single sheetsforwarded to the folding mechanism in correct timed relation with the products of the press. The number of sheets in the multiple sheet may, of course, be varied. and the mechanism whereby the multiple sheets are cut intosingle sheets and forwarded in proper timed relation may also be varied within considerable limits. The sin 'le sheets, however, which make up the multiple sheet will be of a number depending on the particular prod not being produced'by the press. For instance, where the product is once collected, the multiple sheet may include three single sheets and these sheets will be cut and forwarded at intervals of a sheet length. here a product is, however, twice collected, the multiple sheet can be made up of two sheets which will be cut and forwarded at intervals of a two-sheet length. Where the product is not collected a multiple sheet two sheets long can be employed.

Referring first to Figs. 1, 2, 3, and (l to 11, inclusive,'the mechanism illustrated is capacitated to cut a three-part saeet into single sheets and associate these single-cut sheets with a'press product which has been once collected, that is, in which two products have been collected together. The multiple sheet in this instance is made up of three single sheets, s a 5-. These sheets may be similaiaas covers or inserts, or i ay he of any desired character. dependin upon the products with which they are to be associat ed. In the particular arrangement shown these sheets follow each other in line and are fed into the i'nachine in the direction of the arrow a! (Fig. 1.), from an flilf iiilldfld sheet-feeder of any desired or usual type, this not having bee: illustrated, as being unnecessary for an understanding of the invention. The multiple sheet is fed between lower forwarding tapes 9, (Fig. 2), passing over pulleys 12 on a shaft 13 mozmted in the side frames 3 of the machine and a pair of upper tapes 14-, 15, passing ever put leys 15 on a shaft 16. supported in hangers 17, securedto the side frames 3. The lower tapes pass at their other ends over pullevs 18 1) on a shaft 19 secured in the st 'dcr eo-opcrat pass over pulleys 20, 21 on a shaft 22, carrled in bearin s 23 on arms 24 on a rock shaft 25 suitably supported in the side frames of the machine. This shaft has an arm 25 connectcd by a cam-operated rod 26 to lift the pulleys 20, 21 at suitable times to free the sheet. If desired, the upper tapes may be omitted, the pulleys 20, 21, then ope'ating only as a drop roll to control the sheet.

The sheet is forwarded by the tapes against a stop 27 located behind the pulleys 20, 21, by which the sheet is properly aligned. Aft-er aligning the stop is dropped in any suitable manner and the sheet is forwarded to the cutting mechanism. These parts referred to are driven through connections hereinafter referred to.

The cutting mechanism may be varied within wide limits and depending on the number of single sheets into which the multiple sheet is to be cut. In the construction shown in Figs. 1 to 3 and (3 to 11, the cut ting; mechanism is in the form of a pair of cylinders 28, 29, the cylinder 28, in the par ticular constructimi illustrated, being the cutting cylinder, these cylinders being mounted on shafts 30, 31, suitably journalled in the side frames of the machine before referred to.

When a three-part multiple sheet is to be cut into single sheets and these sheets are to be associated with a product once collected, the sheets are forwarded, after bein r; cut,

at intervals of the length of one sheet so to provide for association with the product at the proper time. lVhen this construction is en'iployed, the first sheet is out and forwarded directly to the folder. The second sheet is controlled, as by detaining a suiiicient time for a sheet length to have passed and is then forwarded. The third meet is from. it by an interval, equal to the lif' lll of one sheet. The second sheet is detained by either the cutting cylinder or the cylintherewith and the cylinder is, therefore, made of such size the. by the time the head end-of the detained sheet reaches the she t path and follows the other sections, it will be separated from the third sheet. wl'iich has preceded it. by an. interval equal to a sheet length. in the particular coustrimtion shown in Fig. 1' the sheet is detained by the cutting cylii'uler. This cut- "ti g cylinder 28 and cooperating abutment vc linder 29* are 'th ee times the length of the sheet and the cutting cylinder is provided with a pair of cutting knives 32. 3?}, these ltnives being spaced apart 120. These cutting knives cooperate with the usual cutting woods or rubbers 34:, 3., n-ovided on the cylinder 29. The cutting: cylinder 28 is als provided with sheet-taking; devices. there slmebtalting devices being; in the form of llll sheet 8 eno-see arranged behind and closely adjapins cent the cutting kmres. These pins are mountedon arms 37 operatcdin the usuul manner to project and withdraw the pins. The cutting cylind'e' is further provided with three sets oi? lingers 38, 39, 4:0, which are placed 120 or one sheet length. apart, the function of these lingers beingto prevent the li st and third sepi-u'ated. cover sheets from following; around the cylinder and to guide them into theshcct path to the fold ing' mechanisn'l.

lVith the construction so i ar described it will be apparent that the sheetis out into three single sheets and these sheets are il Olrworded inpredetcrmined timed relation to the :foldcr, being segnrratcd by an interval equal tothe length o l one sheen that is,-equnl to the time ol? once collecting the product on the collecting cylind r. The course of the sheets is diagranunatically shown in 6 in ll. -[iolltuvs i I Referring to those figures, a multiple sheet made up of the sheets s, .9 cfi'is just being lied to the cutting and detaining cylinders. The sheet. is'advanced the length of the Atthis timethc cutting knife severe the sheet 5 and the pins 36 impale the leading edge of the succeeding sheet 8 as shown in Fig. 7. Fig. 8 illustrates the position of the sheet nftcrthe cutting cylinder has made one-third: of a revolution. l ihen the parts are in this" position, the sheet has been taken around the cylinder the length of the sheet 8 and the cutting knife 32 has :u'rivcd in position to sever the sheet from the succeeding sheet The sheet a is now allowed to pass between the cutting cylinders and is SIZJILCt-Ellflfllll the sheet 8 one sheet length, as shown in dotted lines in Fin. 9, the cutting cylinder QShaving mode two-thirds of a revolution. The last onethird of a revolution of the cylinder per- 5' omits the sheet 8" to ud'vzrnce a sheet length,

. which time the pins 33 are withdrawn hour 1 h 0 sheet and the sheets tolh-i'w's the sheet 8",- being spaced. therefrom a sheet length, as shown in dotted lines in Fig. 11. All succeeding multiple sheet, it willbe under stood, will. be held by stop 27 for the distance of n. multiple sheet length, as indicated by dotted lines in Fig. 8. so that in the soquence of operations the single sheets are always spaced apart one sheet length. As the second multiple sheet approaches the cutting cylinder, the parts will again resume the position shown in Fig. 6 and the operation be repeated.

It will be understood that the stripper lingers 38, 39, l0, operate'at the proper time to strip thesheets s s 8 and prevent them from following around the cylinderso that the 7 continue in a strai ht nth direct to the associatingmechanism. From the cut- T-l'iis run may be briefly described as i ting cylinders, the sheets are forwarded through guides 4-1 by a pair of forwarding rollcrs lfl', ski-3., and a secondupair of forward, ing rollers which may} include rolls 4d and the cylinder 8., before referred to.

In; the construction so far. described the sheets are associated; with the product which. has been once collected, that is, two products are nssociatcd on. a; collecting cylinder.

In. Figs. l. and, 12to 1'? there is shown a construction which may be employed when a separate sheet is to be associated with a product twice collected, that is, three products associated onthe collecting cylinder. lf-ic lierring to these figures, the sheet which is ted inby the uwill be a multiple sheet, such multiple sheet. comprising two sheet lengths. lll' here the product is twice collected, these sheets must. be 'l orwarded spaced apart a distance oitwo single sheets and the multiple sheets will be fed to the cutting: c 'lin'ders spaced apart two multiple sheet lengtl-is. Referring tosl'iig. 4:, there is show a cutting cylinder 4&5 n'iounted on a slnril't 4-6 and provided with a cutting knife l7. Cooperating with this cutting cylinder is a. cylinder 48 mounted ona, shaft 49 provided' witl'i. cutting; wood: 50; Each of those cylinders is of a circumference equalv to t 1i .2. the length of a single sheet. Vfhere, as in the present instance.,tl'1e cutting cylinder is the detaining; cylinder, it-is provided with a. set of sheet-taking devices, as pins 51, suitably mounted on arms 52 and thecylinder is also provided with two sets of stripper fingers and 54, these stripper lingers beingiplaced; 180. apart and one set being placed adjacent the sheet-taking pins 51. i

The sequence of operations in thisrun of the sheets is shown in FigsiQ to 17. In Fig. 12 a multiple sheet consisting; o'fnthe sheets a, ais shown as forwarded to the cutting cylinders and the sheet (I, is just being cut oil by the cutting kniitc 4:7. sheet a taken by the pins and carried about-the cylinder. After the cylinder has made a complete revolution the sheet a, is advancedtwo sheet lengths, at which time the fingers'have released the sheet a from the pins and the sheet: a is free to follow the sheet a. As the succeeding; multiple sheet made up of the sheets 2'), 7 is held by the stop 27 four single sheet lengths, as shown in Fig. 12, the single sheets are for warded to be associated with the collected product spaced apart a distance of two sheet lengths, which gives time for the collecting cylinder to twice collect the product before the sheet arrives for association therewith.

In Fig. 5 there is shown a combination of the cutting mechanism which is shown in Figs. 3 and 4 and which may be employed under some circumstances there is provided. a. cutting cylinder As here shown.

mounted on a shaft- 56. This cylinder is like the cylinder 28 of Fig. 3 and is provided. with cutting knives 57, 58 and a set of sheet taking devices, as pins 59, mounted on arms This cylinder is also provided with three sets of stripper fingers 61, 62 and 63, two of which are located adjacent the cut ting knives, the three sets of fingers being arranged at an. angle of 120. Cooperating with this cylinder is a cylinder 64 which has a circumference equal to two single sheets. This cylinder is provided with a pair of cutting woods 65, 66, spaced 180 apart and mounted on a shaft 67. This cylinder is also provided with a set of sheet-taking devices, as pins 68, mounted on an arm 69. The cylinder is also provided with two sets of stripper fingers 70, 71, placed 180 apart and close behind the cutting woods. hen a triple sheet is being used the upper cylinder 55 acts as a detaining cylinder, the pins on the lower cylinder being silenced. .Vhen, however, a double sheet is being used the lower cylinder 64 acts as the detaining cylinder and the pins on the upper cylinder 55 are silenced.

Under some circumstances it may be desirable, particularly for heavy sheets, to provide a cutting mechanism in which the cutting action is effected by a shear out, such a cut'being produced by knives projecting from the cylinder and having bevel cutting faces. I Vhere, however, such a cutting mechanism is used, because of the knife arrangement, the cylinder cannot function as a detaining cylinder. Consequently, where such a cutting mechanism is used, a separate detaining cylinder is provided. Such an arrangement is diagrammatically illustrated in Fig. 18 in which there is provided a cutting mechanism including a pair of'cutting cylinders '72, 73, provided with a pair of cutting knives 74, 7a. In the particularv construction shown in this figure, the mechanism is operating on a double sheet, that is, a multiple sheet made up of two single sheets. To properly space these sheets a sheet'length apart there is provided a detaining cylinder 76 provided with sheettaking devices, indicated at '77, this cylinder being the circumference of a single sheet. For forwarding the sheet from the cutting cylinder to the detaining cylinder the-re is provided a pair of forwarding rolls 78, 79.

In Fig. 19 there is shown a construction operating similar to thatv shown in Fig. 18. In themodification in Fig. 19 the cutting knife 80 is a reciprocating knife cooperating with the block 81 to sever the sheet. In Fig. 20, is shown a further modification which may be employed under some circumstances. In this modification there'is shown a reciprocating cutting knife 82 and cooperating with a block 83 which cuts the first sheet which is fed on its way by the forwardspeeds.

ing rolls 8 1, 85. In the modification shown in this figure insteadof a cylinder for detaining the second single sheet there are provided detaining fingers 86 which hold the sheet against a suitable abutment, as the plate 87. After the first sheet has been for-- warded a sheet length these fingers are opcrated in any suitable manner to lift and a drop roller 88 forwards the second sheet to the forwarding rolls 8 1, 85, the knife 82 having been lifted out of the way.

In the construction so far described the single sheets separated from a multiple sheet are associated with the collected product and the timing of the sheets is effected, in the specific mechanism illustrated, by detaining the sheets. In some instances it may be de sirable to associate the sheets with an uncollected product, that is, a product coming directly from the press which is not collected and which, therefore, is forwarded to the delivery substantially continuously. I Vhere' this is to be done, the single sheets must be associated with the product substantially continuously, there being but 'a small space permissible between the successive sheets corresponding to the small space between successive products as they come from the press. Consequently, timing of the sheets to effect proper association with the product must be effected in a somewhat different way, and a mechanism is provided by the present inventionfor doing this. In most sheet feeders the paper or surface speed of the feederis somewhat greater than the press speed, that is, the actual feeding movement of one sheet by the feeder is faster than the product speed of the press. This fact is taken advantage of by the present invention to feed the sheets in proper timed relation with an uncollected product and two ways doing this are illustrated in. Figs. 21 and Referring first to Fig. 21, there is provlded a long pathwayfor the sheets and means for forwarding the sheets along this pathway, these means operating at different In the construction shown, there is provided a sheet-forwarding mechanism including tapes 90 which pass over pulleys 91, 92, on shafts 93, 94. These tapes are operated at the high surface speed of the sheet feeder from which the sheets are forwarded. in the direction of the arrow. The sheets are double sheets, that is, each sheet consists in length of two singlesheets. These sheets are forwarded by the high speed tapes against a stop by which the sheet is jogged or aligned. The sheet is then forwarded to a second forwarding mechanism which operates at the press speed which, as stated, is lower than the surface speed of the feeder. These forwarding means include tapes 96 passing over pulleys 97 on the shaft 94 and pulleys 98 on shaft 99. The

tapes. rom the tapes 96 the sheets I to a cuttingmechanism. indicated as a p:

may be desirable to utilize "iilll 2513110 me'clr an-isin 1 O1 fl collectedproduct aspreviously described. The cylinder 102 is, therefore, provided with pins 105. Products are associated at a pair of rolls 106,107, and the roll 107 may, itdesirable, he-a coilectingcylinder. With I this construction, after the mechanism starts in operatioma substair tie-11y continuous stream'o't sheets is fed to the rolls 106, 107, because, as the paper speedof the feeder is greater than'the paper speed of the press, the BllGQ'tS-llS-NQ a chance to catch up with each other and the tape pathways are made of such length as to permit this. twill be understood that the multiple sheets are*for'warded at the high shortening fthe "machine.

lower iitorwarding mechanism includes a t speed of thy-feeder until the. tail of-the sheet has passed the-drop roll 100, :it which time they arebrought under the control of the tapes running at press speed. The pathway for the sheets sh own in F 21 may he inconvenient :in some instances because of its length. Where pressroom conditions, "therefore, require ashorter path way, shorter mechanism and arrangement, *suchas shown in Fig.22, is provided. In the construction'here illustrated the multiple sheet-s 'are fed in the direction of the arrow from'thefeeder alternately to an upper and lower sheet-forwarding- 'mechaiiisrn, the mechanisms being superposed and thus As illustrated there 'are provided upper forwarding tapes 103 whichrpa'ss overpulleys "109 on n shatt 110 and pulleys 111. on. a-sha'ft 112. The

101' tapes1'13 whiclrpass over pulleys 11% on' the shaft 110, guide pulleys 115 and pulleys116 on a or shaft 117. This lower mechanism also includes a set'of tape .8, which pass overrpulley-s 110 on :1. shalt 110 and over pulleys l2l.,'Sll!1lltill(') thepull-eys 115,;and over guide! pulleys 122, the tapes 118 and 113 acting as gui'deway for directing the sheets tothe lower sheet pathway. The sheets are alternately directed to the lower pathway by means of a switch 123 which operated in 'a suitable way to effect this switching function.

"These upper and lower sheet-forwarding mechanisms run at the slow speed of the press and the sheets areforwardellto them at thehigh speed of the feeder. As the ,sheets are forwarded'they are brought up against upper and lower stops 124, 125, by which the sheetsare "From the stops the sheetspass to cuttingmechanism, which may :be reciprocating cutting knives 126, 127, and from the cutting knives pass to tin'ii-ng rolls 128, 1-29, 130, 13-1. Witli this construction, an upper multiple sheet is fed to the cutter 12']- and dividcdointo :two sheets which are fed to the-timing "rolls 123. 129, andv associated with two successive products at that time. In the meantime, a second sheet has been forwarded to the lower cutting knife 126, theredivided into two sheets and associated with the next two products, so t-hat the sheets may be continuously associated with uncollectedproducts.

Any suitable niechan isnrmay been'iploycd for driving the parts of the machine. As illustrated in Figs. 1 and 2, various mechanisn'i are drivenby a power shaft 132, this shaft being driven from any source notxillustrate'd. This shaft is suitably supported in side fran'ies 3 of the machine and outside the fran'ie carries a driving 'gear 133. In-

side the frames the shaft carries a gear 13 1 which incshes -with agear 135 on the-shaft 136 which carries rolls 141, thus driving-these rolls. fl he gear 133 is in mesh with an in termediate 137-ona stud l38moin1ted in side frames of the machine. ll'hisintermediate is in mesh with and drives a 1pinion 139-on the end of a shaft 140011 which the rolls 13 areonounted. l his shaft 140 also has a gear 111 which meshes with a gear 112 011 the shaft 1 113 on which the roll 42 is mounted.
